Mike buys a perpetuity-immediate with varying annual payments. During the first 5 years, the payment is constant and equal to 10. Beginning in year 6, the payments start to increase. For year 6 and all future years, the payment in that year is K% larger than the payment in the year immediately preceding that year, where K < 9.2.
At an annual effective interest rate of 9.2%, the perpetuity has a present value of 167.50.
Calculate K
Computation of Discounted cash flows
Year | Dividend | Disc @ 9.2% | DCF |
1 | 10 | 0.915750916 | 9.157509 |
2 | 10 | 0.83859974 | 8.385997 |
3 | 10 | 0.76794848 | 7.679485 |
4 | 10 | 0.703249523 | 7.032495 |
5 | 10 | 0.644001395 | 6.440014 |
Total | 38.6955 |
Let the Growth rate in dividend be K%
The PV of future cash flows from year 6 to year infinity = Dividend in 6th year/I%-K%
(10+10*K%)/9.2%-K%
Present value of first 5 years+ Present value of year 6 to infinity cash flows= Present value of the perpetuity =167.5
38.695+(10+k%)/(9.2%-K%)= 167.5
(10+K%)/(9.2%-K%)=167.5-38.695
(10+0.1K)/9.2%-K%=128.805
10+0.1K = (9.2%-K%)*128.805
10+0.1K= 11.85006-1.28805K
1.38805K=1.85006
K% = 1.3328%
Hence K = 1.3328%
